Batman

Batman looks like a hunched, lean man, covered in short black fur and with large membranous wings. His lips, pulled back in a sinister smile, reveal a mouth lined with crooked, needle-like teeth. His eyes glow red like burning embers of hate. Long arms end in cruel claws, and the air around him shimmers with waves of intense heat.
Batman is a being of pure savagery and hatred—a vile demon that holds sway over the lightless places of the underworld. In the deep recesses of the earth and the sewers connecting to the surface, he waits restlessly until the slow creep of night engulfs the land, releasing him to feed and spread terror.
